id say its more of practice makes perfect as i know a number of strains have been used, some yielding almost 14 oz's per lady. the buds were almost as wide as my face, never seen buds like it in my life. amazing results without the monitoring of temp, RH, ph or EC. i wish i could call him flukey but iv never known him to get any problems or bad results! always consistent. hopefully some of you experienced folk can get similar results and share some tips. itd sure be a nice change to pulling 1 oz per lady.
